ldap_add: Invalid syntax (21) – fix

January 21st, 2010 No comments

This error was driving me nuts:

ldap_add: Invalid syntax (21)
additional info: objectClass: value #0 invalid per syntax

despite looking at my ldif a hundred times, until I relized my perl script added white space at the end of the line ….

print "objectClass: top\n";
print "objectClass: person \n";
print "objectClass: organizationalPerson \n";
print "objectClass: inetOrgPerson \n";
print "objectClass: mozillaOrgPerson \n";
print "objectClass: evolutionPerson \n";
print "objectClass: simpleSecurityObject \n";

once changed to :

print "objectClass: top\n";
print "objectClass: person\n";
print "objectClass: organizationalPerson\n";
print "objectClass: inetOrgPerson\n";
print "objectClass: mozillaOrgPerson\n";
print "objectClass: evolutionPerson\n";
print "objectClass: simpleSecurityObject\n";

The ldap gods were smiling again, hope this saves someone some time.

Linux HA – CRM commands

July 22nd, 2009 No comments

Small reminder as I always tend to forget these :

Dump the CRM cib db :

cibadmin -Q > cib.backup.xml

Modify a resource , dump the cib, modify the xml for the resources and then import using cibadmin -M

cibadmin -V -M -o resources -x modified_resources.xml

Add a resource , create the xml for the resource and them use -C

cibadmin -V -C -o resources -x new_resource.xml

Move resource from one location to another, -f to force it …

crm_resource -M -r resource -H host
crm_resource -M -r resource -H host -f
